| 目的：研究聚合瓷嵌体修复活髓后牙大面积牙体缺损（Big dentin defect，BDD）中的临床疗效。方法：从2009 年6 月到2011
年6 月，于我院牙科就诊病患中，后牙的牙体缺损大于1 个牙尖者有80 例，共87 颗牙齿。以数字法随机分成治疗组（41 例，46
颗）及对照组（39 例，43 颗）。对照组以高嵌体方案治疗，治疗组以聚合瓷嵌体方案治疗。对比两组一周以及一年后修复体评价情
况。结果：治疗一周后，治疗组在美观方面显著优于对照组，差异有统计学意义（u=2.038，P＜0.05）。而两组对比术后敏感以及牙周
状况等数据，差异均无统计学意义（u=1.132，1.389，均P＜0.05）。治疗一年后，治疗组在修复体折裂以及美观等方面显著优于对照
组。差异有统计学意义（u=3.138，2.874，均P＜0.05）。两组在继发龋和边缘着色，邻接以及肩台适合和牙周状况等方面对比，差异
均无统计学意义（u=1.132，1.374，1.454，1.268，1.366，均P＜0.05）。结论：聚合瓷嵌体对于活髓后牙BDD的修复效果较为显著，可
较大程度恢复病患牙体功能，减少继发龋的发生率。不易折裂又更加美观，值得临床推荐。 |

| Objective:To study clinical effect of polymeric ceramic inlay restoration of vital pulp posterior teeth with big dentin
defect (BDD).Methods:From June 2009 to June 2011, patients in our hospital tooth defect of posterior were greater than 1 teeth cusp
had 80 cases, a total of 87 teeth. Digital randomly divided into the treatment group (41 cases, 46) and the control group (39 cases, 43).
The control group used with onlays regimen, while the treatment group used with polymer ceramic inlays, compared two groups of one
week and one year after the restoration evaluations.Results:After one week of treatment, the treatment group in aesthetics was
significantly better than control group. Difference was statistically significant (u= 2.038, P <0.05), comparing the two groups with
sensitive and periodontal status and other data. The difference was not statistically significant (u= 1.132, 1.389, all P <0.05). 1 year after
treatment, the rank sum test, the treatment group's aesthetic and restoration fracture was significantly better than the control group.
Difference was statistically significant (u = 3.138, 2.874, all P <0.05). The two groups’comparison in secondary caries and marginal
discoloration, as well as the adjacent shoulder fit and periodontal status and other aspects. The difference was not statistically significant
(u = 1.132, 1.374, 1.454, 1.268, 1.366, all P <0.05).Conclusion:Polymeric ceramic inlay restoration of vital pulp posterior teeth with
BDD's repairing effect is more significant, patients can resume a greater degree of tooth function, reduce the incidence of secondary
caries. It is not easy to fracture and is more beautiful. It is worthy of recommendation. |
